Jeran is originally from Neopia Central, but as a child he stumbled through a magical portal that teleported him back in time to Meridell. There he grew up to become a knight who played a pivotal role in both of the Meridell-Darigan wars. Eventually, he was also joined in the past by his long lost sister, Lisha.
During the Void Within plot, Jeran was a victim of the Grey Curse, and looked more like this:

The world is full of danger... but there is always hope.
As a knight, I try to uphold certain moral standards like justice, compassion, and I do try my best to forgive... I admit it though, I do take a certain joy out of smacking a Kass plushie with a bat every once in awhile. Care to join me?
Can you roll your way through to surpass us all?

You may have won this time, but I only get stronger...
There was a painting in the Neopia Central museum depicting Jeran. In it, he was called Sir Borodere, which his Collectable Card was also originally called. It is possible from his age that he was born in 11 BN, but his time travelling means that this date may not be accurate.
