Dal Shabet

Since you're interested in Rkul's fate, here's what happened after your departure: the explosion of Ivy's bomb caused significant damage to both Dalingr and Rkul, weakening them considerably. Then, Merestianna finished them off with Ivy's sword; considering the amount of energy she absorbed that day, it was quite easy.
After that, Nevermore was rebuilt under the leadership of the brilliant inventor, Ivy, who ruled the city alone, with Merestianna helping her to resolve all the issues in this endeavor. Subsequently, this city would become a center for technological development and eventually the capital of the old world.
There's also Ayros and his teacher, the first's sister, Vaironisa, but I'll tell you about them if I ever decide to write about Laust's further adventures.
