The Angel's Chosen

The Angel's Chosen (also known as a Vessel) is a small humanoid figure that represents the player. They can be customized with decals that don't effect gameplay, like masks and wings.

Appearance
The Angel's Chosen is pale in appearance. Their body is made out of a white concrete-like material (which the Observer confirmed was stone) and areas like their mid-section, a dot on their chest, and another 3 dots (we assume are eyes) on their head are a glowing white. When first starting the game, the Angel's Chosen will also have simple wings which glow with a light blue.

As the player collects Sacred Flames, the amount they have will correspond with the amount of flames following the Angel's Chosen. When all 7 flames are collected, they will form a circle with one flame in the middle.

Compared to NPCs like Umbra and Lux, the Angel's Chosen is about equal to them in size. Other NPCs like Young Man Coin, the LoreKeeper, and the Dark One (and possibly Old Man Coin) outsize the Angel's Chosen by a moderate bit to a significant amount.

Trivia

 * It is possible that the Angel's Chosen is not an angel themselves, as they don't quite resemble the one currently known angel, the Lorekeeper.
 * A piece of dialogue from Young Man Coin states that the Angel's Chosen are "servants to the angels".
 * The description of one of the Angel's Chosen's masks says that only the "angel's most trusted vessels" wear it, also possibly implying the Angel's Chosen is not an angel.
 * A piece of dialogue given by the Observer at the end of their quest line states that the Angel's Chosen are stone vessels created by the angels, imbued with life through human souls.
