Name: Elena Lincoln
Gender: Female
Age: 206 years old
Species: Ghost
Ability: Bypassing the borders between the Dream World and the material one. Through this, she can access the outside world, where she spends most of her time. To a certain extent she also seems to be able to change her outward apprearance, though this is not touched on during the events of AA.
Location: She's a wandering ghost and doesn't really have a fixed haunt, but can be seen hanging around the Hakurei Shrine a lot. When she pays visits to the outside world she's most often spotted in the White House. Elena for President '16?
As for her house, well, she quite literally
lives under a rock.
Occupation: Ex-President of the United States of America. She occasionally jokes about running for President again, although I'm pretty sure ghosts aren't allowed to serve in office.
Originally from: Kentucky, USA. Famously born in a log cabin.
Personality: Generally pleasant and good-humoured, although she can get clueless and insensitive at times. She doesn't understand 21st century politics, either.
Spellcards: America "Fourth of July Fireworks", Light Sign "Crystal Laser", "The Gettysburg Address"
(Secondaries)
Danmaku: She has nonspells that look like this. <snip>
<Tengukami> No hotlinking, if you please. And do reconsider whether using the Confederate Battle Flag is really a good idea.
Special/sacred items: None really, besides her hat if you want to count it. However, she's seen holding a box of popcorn and also implied to have been eating from it (it's the reason why Tesla's electrically transmitted raijuu poison didn't affect her, according to WaHH, the cure for a raijuu's poison is corn).
Relationships: Acquainted with Reimu, and possibly also with Doremy due to her frequenting the dream dimension. Probably recognizes Benedict Arnold from history books, and befriends her after the events of AA.
Likes: America, her hat (she outright quotes a line from Koishi's Heart-Throbbing Adventure), wandering around observing things, and possibly popcorn.
Hates: Discussing politics. Also dislikes slavery and abuse (and at the same time, Toko). Strangely does not have any sort of aversion towards Confederate flags and even adapts them for use in her nonspells, which is odd considering the fact that she had been on the side of the North during the American Civil War.
StoryElena is a lingering ghost of a dead US President (I'm sure I don't need to name him) that failed to pass on to the afterlife due to a general sense of feeling that she still has unfinished work to do, although she can't exactly remember
what. She also can't remember most of what happened to her during her life owing to her death from a serious head injury. During the events of AA, ghosts of the damned started appearing out of hole in the ground connecting to Hell. These spirits caused the residents of Gensokyo to feel depressed and moody with their presence, with the exception of Elena who was strangely unaffected (later revealed to be due to the popcorn she had been eating). She eventually decided to help the heroines out by exploiting her ghost-ness in order to blend in with the sinners' ghosts for the purpose of gathering information about them. It turns out that they were not on land to cause trouble, but rather, their appearance signified a call for help because Hell was currently in a state of major trouble.
Yep, totally not blatant self-insertion right there. I'm going to Hell for this (pun intended). :'P
