Hey all!
It's been a long time, but I'm finally back and writing an actual story:
It's a bit of a lite-litRPG, wherein the MCs do have a System, but it's explicitly an in-world construct, and one of the MCs is an archmage with a specialization in System Engineering. Book 1, The System Must Live, has a strong focus on getting their Systems working again, as they all get stuck at level 1 thanks to their Jump.
I hope that, if it sounds interesting, you feel like checking it out!
