Piru
Piru was the life-partner of Chromium Rhuell.
History
Both Piru and Chromium were servants of the planeswalker Geyadrone Dihada, and were summoned by her to fight Dakkon Blackblade. Dakkon tried to put mind-control on Rhuell and ordered him to kill Piru, but since Elder Dragons are nearly as powerful as planeswalkers, he failed. Rhuell started to drain away Dakkon's energy, but was sent to an unknown location by the planeswalker at the last moment. Piru then fought him, but was killed when Dakkon stabbed her with the Black Blade. This released a massive energy blast that created the Dueling Chasm of Golthonor. Geyadrone Dihada absorbed a lot of Piru's energy and had in fact planned the dragon's death all along: she wanted the power of an Elder, but knew this could only be gained when such a dragon died. Since they where almost impossible to kill, she had Dakkon forge the Black Blade and then manipulated him into fighting and killing Piru.
Lesser Elder or Elder Dragon?
There is some debate whether Piru was a true Elder Dragon, or one of their direct descendants, a Lesser Elder. Some sources say there where only five Elder Dragons that survived the Elder Dragon War: Chromium Rhuell, Nicol Bolas, Palladia-Mors, Vaevictis Asmadi and Arcades Sabboth; which would suggest that Piru was a Lesser Elder. Some of later Magic comics, however, claim that Piru is the sixth Elder Dragon, something that would be likely since it seems odd that a race as powerful as the dragons could have grown from five close relatives (the five Elder Dragons are all relatives; all, save Asmadi, their cousin, were siblings). Furthermore, Piru seems to be colorless, making it the "sixth color" not represented in the others.
