Guess SUSHI is on the menu tonight.

  DEEP DWELLER.  
Vardavar was a long forgotten laboratory within the Sirensong Sea. This Allagan lab researched alternative applications of Eikon-draining technology. The biggest project was the sword Vishapakagh, but there were also numerous pods of chimerical experimentation. There was an attempt to make weapons that would create Eikon-shifting soldiers based on weaponry alone -- but similar to Zana -- the project ended in failure.Unlike her successor, V500 was never a parasitic siren. It is no coincidence that the lab was malms away from a ship graveyard. The first attempt in creation allowed for Zana to look more Hyur than fish.Nowadays, V500 is known by Zana Vardavar. She walks the lands of Eorzea where she welcomes assumptions about being Au Ra in a land that is none the wiser about the scaleborn race. Zana was gifted her name by a 'Nightfall Company officer.' In truth, he was another thief in pursuit of treasure. Although V500 was written off as damaged, forgotten, and decayed, her new band of companions were able to open her pod with the ID card.

  SILVERWINGS EXPEDITION.  With a tall-haired Xaelic man dungeon crawling along the bottom of the ocean, would you ever expect him to return with a sword and a slave?A pirate-turned-Justicar utilized a false Allagan identification card in pursuit of entering the ruins of Vardavar. The party of bandits put on an embarrassing display. After wiping three times, they were able to defeat V501 and continue onward to locate relics from a Meracydian primal. Although the sword of Vahakn was a great gift in itself, there was something far greater within the forgotten laboratory. Something sentient.
