Depths of Tytheus

Depths of Tythus is the first expansion in the Grappleverse. It was released in 2022. It introduced the story of the necromancer Qirauz, beginning a story arc that spanned a further five sets. Set on the underwater plane of Tytheus, Depths of Tytheus explored deep-sea tropes and had a mechanical focus on energy counters and modified creatures.

Set Details
Depths of Tytheus contains 259 cards (10 basic lands, 101 commons, 80 uncommons, 53 rares, 15 mythic rares). It features the return of energy counters and modified creatures as major mechanics, along with the ability word Discover which allows you to fetch cards from outside the game to represent the discovery of rare treasure beneath the waves.

Set Introduction
Beneath the waves, beneath a forever clouded sky, but not beyond reach.

On the ocean world of Tytheus, it’s never safe to dive too deep. The aquatic elves of Blackwater know too well the horrors that lie buried at the bottom of the seas, and carefully monitor the expeditions of surface-dwelling humans into the depths to ensure they never stray too far. The predations of benthic leviathans and the animalistic merfolk, together with the watchful eye of Ihosk, the long-lived king of Blackwater, have so far kept the briny deeps safe enough. But the human fleets of Deepdive and Skyside, led by the brash and prideful captains Pundar and Dusath, yearn to expand the remit of the human societies clinging to the precious few rocks that make up dry land. Their steam-powered vessels plumb ever deeper in search of material wealth and the lost detritus of millennia, and Ihosk’s cunning and guile are needed now more than ever.

Storyline
There is promise in the unknown—promise, and fear. Under the all-encompassing seas of Tytheus lie great riches, and also the terrifying darkness of the uncharted depths. The undersea kingdom of Blackwater, ruled by the elvish king Ihosk, maintains its borders against the marauding tribes of feral merfolk and the predatory might of great seabeasts, but its territory has been beset by the inquisitive humans of the surface world. Two great factions of exploring menfolk have breached the depths, and the bathyscaphes and submersibles of Deepdive and Skyside comb the brine for plunder and mineral wealth.

An ancient relic sits in deep and primal silt beneath the surface, awaiting its former owner. The necromancer Qirauz has hunted down this quarry across the multiverse, finally bringing his dark skeletal forces to bear upon Tytheus to retrieve the Heart of the Sea, torn from his possession in millennia past. The great planeswalker cared not for the consequences of his actions, leaving with his recaptured loot as quickly as he arrived. However, in the wake of this disturbance, something slumbering was awoken, and the departing necromancer gave not even a backward glance as the elder god Daugan rose from his eternal hibernation.

Primordial and unknowable, Daugan and his brood of deep-spawn children rose from the thick slime of the sea floor, destroying all in their wake. Faced with the threat of an ancient god, the civilisations of Tytheus were forced to rally together, and now the renegade prince Shilok, son of Ihosk, usurper of the throne of Naggorash, stands as a figurehead of resistance against the eldritch horrors of the deep.
