Just how well versed in the lore of the nerd can one person become? I will demonstrate. Behold the nirnroot:
Only those who truly believe in the power of Geekdom Come will ever find a real nirnroot. This one was growing in the forest near our house, likely feeding off Poindexter rays coming off of our television from watching late night Star Trek reruns.
Mystic herbalists claim that the nirnroot is very rare, but I don't grok that. The thing glows in the dark and emits a dull ringing sound, which seems to me way different from any other forest creature I can think of. You can't miss them. Some people grow them in pots, but that's a lot of effort compared to just looking for nirnroot plants near water.
State of the art for the 2006 geek, for the non-dweeb the nirnroot is a feature of the old video game Elder Scrolls: Oblivion published by Bethesda Softworks. Their game designers get the true credit for coming up with the nirnroot plant.
Any resemblance between a nirnroot plant and a western skunk cabbage may or may not be coincidental. While either plant may be edible, JSVB does not reccommend consuming them.
