Kinda have figured out what to make him)

A void knight is a creature filled with void essence, despite being with void it is still completely a dark creature. It's unsure who created them and their entire purpose are, but they are all apart of their own order.

Some speculate the void knights were the opposite of the Iron Lord, but that is not entirely true although they have fought irons lords before.

Plus Reggie is not a real guardian, after he was banished and became a cursed void knight he took on the form of a guardian, and made a fake ghost to blend in with them.

Void knights are rare to encounter, and usually docile unless provoked. Other accounts of their presence have been seen on every planet, but mostly on desolate planets

Reggie's looks:

Their armor is pitch black with purple void essence engraved in them. Their weapons vary from knight to knight, especially design.

When they are drained of power or light the purple glow from both the armor and sword disappear, making them look like an empty husk. They also tend to be stationary and rarely move.
