How is Dark Messiah connected to Heroes of Might and Magic?

Ah, yes. And one more thing, an epilogue, so to speak, remember?
"Agrael returns to Isabel after many years of imprisonment.
- Railag! You're finally back! Where have you been all this time?!
- Darling, I... - shows off his new armor from Kha-Belekh.
- What?! You're at it again!!!
At this moment, Lianna intervenes, complaining about Sareth and Agrael together, saying that they are both jerks. Both blondes (one is dyed))) attack Sareth and Agrael. Xana and Biara rush to defend them.
- Hey, what's going on here? These are OUR guys!
A general brawl ensues. Sareth and Agrael quietly step aside and watch the female fight in amusement.
- Um... Agrael, is it always like this?
- Yes, Sareth... - his adoptive father sighs. - Welcome to the family... To the madhouse!" XDD
