Knights of Tezoth

Ah, I've seen those posts, but I didn't understand them.

First of all, what does "gave a piece of mirror" mean? I scrolled through 5 or 10 pages, but I don't see anything like that.
Secondly, I remember that post about the head explosion, but who blew up whose head — I thought it was one of the summons.

It's not a piece of mirror, lol.

Inside, the acting lord finds "Iphilla's Lock" as well as information about the entity Anella Blood and the Daughter of the Sun.

the souls of creatures that did not belong to him appeared, which finished materializing and already stood around the pale (which contrasted with her bloodied face) ruler of Osha.

- Who is this? Who the f*** is this??? - The event that had occurred made her completely lose her composure. - Begone to whence you came!

In response, the long-eared one gathered her own blood in her hand and, with lightning speed, hurled a crimson spear at the speaker, instantly killing her.

- Oh. - The white-haired one feigned sadness. - How wasteful of you...

Well, not a mirror, whatever it was. Still don't see any posts where that bastard shares something in exchange for olives.
Who is the white-eared one, who is the long-haired one — why should I have to figure this out?

Apparently I just don't get it. But I'm a regular player, and if I don't understand something, was it ever stated?
