h, one of my favourites topics speculation so ... I love that. For the next cycle, cthulhu is a good bait, for Silas principally, and because after two core-box ancient one ( hastur and yog ) we've got two not core ancients, so perhaps another of the first four of the core would coming, but he could wait a little bit. Another possibily is Mountain of madness / Ithaqua / elder things, because we-ve got the promo 2017 player cards of Arkham Nights in the actual cycle, and those cards have a strong connection to the lore : the box is very feeling like a rich cultist device (Lodge) and the 13th vision is linked to the witchs, and the prophecy of the beginning. So the 2018's promo cards are a plant and a feeling-inuit ally. So the plant because of the adventure feeling of an expedition, with confrontation to natura, albinos pinguins, artic bears ... and the ally for the antartica/artica feeling of a cycle Ithaqua and/or Mountain of madness. So for me Cthulhu or Ithaqua. More cthulhu perhaps.
But I will not stop here : I will say each cycles that can come someday in my mind, and information about each ancient ones I know.
So the two remainings of the core's agents set first.
1 - Cthulhu - sleeping in the Pacific ocean. Linked with fishy monsters, a lot of cultist, and have a power on the dreams.
We could see a start at Arkham, by Velma's diner, and the docks. One for deep one linked, other because of the previous arts of velma's diner. Then, Hospital perhaps, after, been injuried, we are in it with some medecine drugs that give us a dreamish experience. Then, innsmouth for sure. The town and the hotel, with perhaps a visit to an underwater city of deep one in a dream. Then, a chance to visit haîti. And finally, R'hley, the green sunken city where cthulhu is sleeping. A lot of deep-one, star spawn and fishy monsters ( would love sharks).
2 - Shub-Niggurath. Forest and goat linked. Fertility god. Pretty looking like satan by his cult. More naturish.
Arkham forest, with primitiv cult. Perhaps the Ma boarding house, and mud swamp. A place for orphan woman that are in the cult. Then, a celtic place, like Bretagne of France, Scotlands. Then, mi-go planet, yuggoth. Yaddith, a dhole-lurking planet where shub is sleeping, or Harag-Kolath, cavern under arabia another possible location of the ancient. Don't know what would be the point, but I can see fighting dark youngs, dholes, mi-go, Tcho-Tcho. and perhaps the thousand one as an avatar.
3 - Ithaqua. Looking like a gigantic wendigo/Yeti. Cold ancient one.
Arkham toundra ?? don't know. A meteorologic study place ?? Then for sure, that will not be too much in arkham, and more like an expedition. So base camp at the rooth of mountain. Perhaps canada. Then, pretty sure about Mountain of madness. I know Ithaqua and these mountains are not on the same continent, but FFG already did some aproximation for the game, as with Kn'yan under mexico, where lovecraft made it under oklahoma. And for the final, the iced dimension of Borea, where live ithaqua. We would fight the natur of the cold wastes, wendigo, perhaps some gnophkeh, and elder things for sure.
4 - Nyarlathotep. The god to the thousands masks.
No idea to how treat it in normal cycle. Too much nice places to see : china, australia, egypt, kenya, england ... No, saga-style expensions or nothing. Too much masks to use.
5 - Atlach-Nacha, the human-faced spider, weaver of reality. - Or - Nodens, the elder god, greek god looking like and ruler of dreamlands.
The two can be see in dreamlands cycle. For it, some much places : Kingsports the town of dremers, the underworld, the moon, the stairs and wood at the entry of dreamlands, oriab, leng, kadath, celephais, Sarnath, dilath-leen, ulthar, land of mnar, inquanoth. Soo much places that I would not be deceived to see two cycles in it, one for each god. We would fight against gug, bhole, ghast, moon-beast, men and spiders of leng, zoog ...
6 - Glaaki, the inhabitant of the lake, giant spinned-slug. Lurker of the lakes.
He have his own place to be, created by Ramsay Campbell, the England valley of Severn. In this place, lurk this ancient one. He have his own cult, made of sorcerers and victims of his spines : some sorts of undead after that. Glaaki is sometimes in others lakes around the world, occasion to see it in the miskatonic of Arkham, or in Dunwich, or more exotic places. Moreover, the Severn Valley contains others mythos beings, as Y'Golonac and his parasites, the denizens of S'glhuo, Bokrug and Eihort. Not sure of the way they should exploit it, but it would feel like an horrific feeling, more physical than the specters of the actual one. A final in Shagai is possible, because we don't know where glaaki is born, we can imagine what we want.
7 - Tsathoggua, the black toad. sleeper of N'kai.
Yes, even if his name not being dropped in the forgotten age, some cards reference it. He is an ancient one from the ancient land of Hyperborea. A gigantic green continent, savage, and full of sorcerers towns, necromancer, and some dinosaurs in it, like a fanatasy-world. Tsathoggua, like Atlach-Nacha for some, and the father of abominations, Abboth, live in the cavers of the mount Voormithadreth. This mount is supossed to be linked to the blue-cavern of Kn'yan by two ways. First one : by getting dow in the black cavern of N'kai, you must been near ot the Voormithadreth cavern where lurk the ancient one. Second point : The inhabitant of Kn'yan worship it. We visit Kn'yan the blue cavern in the FA Cycle, but just a part of it. There is a city named after the black toad : Tsath. Very technologically advanced, with alien looking like indians, that can teleport and talk in mind. So we would return to see that and the perversion of those, and the fantasy of the hyperborean continent.
8 - Ghatanothoa, the dark one. The bane.
If there is a true bad-one in the ancient-ones, he is. Amorphous being thatcan petrify anyone with single look, even priest of other ancient-one had try to put it down, like a priest of Shub-niggurath (I don't know well this story, so not sure why). He is a living ****, with lloigors as agents. He was worshipped in the lost continent of Mu, that been drowned.
Really don't know how to treat this one, or others like Shuddle Me'l, Abboth, or Cthylla, Cthugga ... But there is surely things to do with them.
