The story thus far, A vanilla santa clause asked two of his elves to go deliver a VERY IMPORTANT BOOK to a certain house in nola. This is them now, or, 3 years ago? I guess since this is supposed to be then, then yeah, three years sounds accurate. The book won't go to the intended recipient for several million years, but let's not get ahead of ourselves, we've got to meet all the leprechauns.
First off-wait, leprechauns...
Let me look, yeah, leprechauns are their intended species. Now, why you chose to call them elves is beyond the realm of this semi-cannon extension of a webcomic, but hey, it's technically required reading material for the og comic since mr Spinny man decided to hit some stupid buttons. Here we are, the list of LEPRECHAUNS we know:
Hook #3 - she has the ability to pull anything in the universe to her
Back ends #6 - she has the ability to move things in the past
Ski11les #11 - he has the ability to traverse anywhere in the multiverse and can carry people along with him
Lie #15 - he has a camera that allows him to pause time
That's it, you only know 4 thus far, but there are 14 left to meet and by the end of this, you'll have met most of them. (I couldn't find a place to put #2, #4, #16, and #18, so I'll leave them anonymous for this)
