#now i'm wondering if aaravos cut out his heart to put in the staff

[raayllum]

Okay so like out of story the dark magic sigil is based on the caduceus, we know this. But in universe, there are only two symbols for the seven sources that include diamonds, like, at all

The Star Primal, with a diamond enshrined in a quasi-semi circle, and the dark magic symbol, with a diamond almost as though the magic is being channelled from it (like the power cyclone), which matches up with Viren / Ziard / Aaravos’ staff

However we’ve also noted the diamond pattern of the interlocking square-ish shapes from the bottom of the dark magic sigil to be in Aaravos’ crown and Katolis’ heraldry diamond pattern

In a series of circles with the Key of Aaravos being the main angular exception

Basically of this tethering Aaravos’ diamond imagery of his literal chest piece and his crown not only to Katolis’ historical heraldry (possibly started by the Orphan Queen) but also to the symbol of dark magic itself, as well as his Key
