The Academy is the training and arming center for Death’s Reapers in Grim Trials. It is where Avelin interacts with mentors and peers, works with crafting systems, takes relationship-building quests, and learns more about the dead who inhabit the game’s afterlife.

What can you do at the Academy?
Official store copy ties several systems directly to the Academy. Avelin can seek guidance from mentors, take quests that build relationships, and unlock advice, knowledge, and support from peers. Crafting is also mentor-linked: battlefield materials are turned into stronger weapons, armor, and consumables with help from practitioners of the arcane arts.
Weapon, tailor and potion rooms
The release-date trailer references three doors leading to a weapon room, tailor room, and potion room, each with a mentor who guides Avelin. This is useful pre-release evidence for how crafting categories are organized, although the final menu structure and exact mentor names should still be checked at launch.
Relationships and story progression
The Academy is also where the roguelite loop reconnects to the coming-of-age story. Relationship quests are not described as cosmetic-only: official text explicitly associates them with knowledge and support. Until the full game is available, the safest assumption is simply that Academy interaction matters and should not be skipped.
