While all the real wizards—er, myself excluded, someone had to watch the acolytes—were away at a conference, one of our students forgot to close the seaside portal before the annual migration. Now our hallways are positively swarming with giant crabs! And, to make matters worse, they seem to have—rather unfortunately—figured out how to use the other portals!

Those damn crabs are causing quite a bit of havoc to the connected towns, if I might say so! Oh, no don’t you worry about them, though. The guards there are more than capable of dispatching the supersized crustaceans. Hah! They’ll be eating crab for weeks! Ah, what was I saying?

Oh, yes! We need you to clear our Academy of the cantankerous creatures! In return, you’ll be able to use our portals whenever you wish in future, and you’ll also be able to keep all the crabs you dispatch.

Shall we begin?

LUKE: The founder of Seafoot Games, Luke's been making maps and RPG games since he was a child, and spent over a decade creating his own game systems from scratch to play with his brothers. That was before he discovered other TTRPGs existed. Now, he paints the realistic grimdark fantasy battlemaps we're known for, helps write adventures as needed, and spends his free time printing and painting 3D minis, as well as working on his forever in-development TTRPG system.

BEB: Luke's wife, Beb's been writing, painting, and graphically designing things her whole life. She published her first book when she was 20, alongside a handful of sci-fi short stories, and was responsible for writing almost all of our adventures until mid 2022 when Steve joined the team. Now she mostly creates the outlines for the adventurer's guides with Luke, graphically designs documents, handles the bookkeeping (or as she likes to call it, bureaucrat wrangling), and manages the website—but she is slowly delegating these responsibilities, so she can focus on raising her and Luke's beautiful son.
