Weshkam - Tumblr Posts

I just found in FFXV Comrades conversation with Cid and Weshkam, where they mentioned the ugly octopus who killed Pelna (i forget the name of that monster) But Weshkam said something there along the Line "Battle began by his sword(Regis's) was ended up by his glaive." And who killed that octopus? Of course our one and ONLY Nyx Ulric!!!
