So I got Oblivion about a year before skyrim came out and I used one character throughout that year; a Bosmer. Fast forward a year and I created the same character on Skyrim and I still play it to this day. However for the next elder scroll (whether it be released in 1 year or 5 years) I want to use the same character again. My main issue is, the time period of the next TES game will most likely be beyond the max life span of a Bosmer (I've read that 300 years of age is considered old for the wood elves).
Basically my question is: is there a lore friendly way to extend the lifetime of my character. I know the Bosmer aren't particularly gifted in the arcane arts, but I was thinking more along the lines of a pure bloodline. Perhaps even with the traditions of the green pact dying out, being exceptionally loyal to the pact pleases Y'ffre and he bestows a gift of extended life to you. Just wondering if any of you had an imagination that could help me out.
Thanks in advance
