Gavril ---- is the name --- Post updated --- oh btw petition for gavril vector here edit: like to sign
Vector sounds good to me, and it goes well with Vertex, in a similar manner to Ford's mid-00s naming system that saw most vehicles start with 'F', but in Gavril's case, it'd be starting with 'V'.
This poor Gavril has been through so many different names than an adopted kid. But makes sense if we are the defacto name committee. Is it the Gavril Damn? Jk
