Sov-El
Elves are haunted by the past. Betrayed in an event they no longer remember, elves have become very isolated, and most refuse to leave their homes on Sovyrian. Sov-El, a mysterious elven corporation, is the only widely known manufacturer of elven starships.
While many manufacturers build their vessels for a single purpose, such as transportation or war, Sov-El accommodates elven isolationist tendencies with sleek but immense ships that replicate Castrovel’s environmental wonders, even reproducing beloved rooms of elvish homes, complete with scenic views. It’s rare for non-elves to serve on these ships, and the elves who fly them rarely leave them, except when forced to by necessity or emergency. Sov-El continues to churn out bigger and better starship weaponry as well, ensuring that no one disturbs the peaceful solitude its elven clientele desires.
