I Know the Reaper

I Know the Reaper is the twelth quest in the Legends of Old questline, and the third in the X-15 segment.
START: Tylious Dawnbane, located in Winterstorm
END: Sera, located outside of Death'kul.
==Description==
Tylious stares at you as approach, his eyes flare up again as he reaches for his axe.
"I have enough on my mind <name>, I thought I told you to leave me alone."
You give Tylious the notes, and give him the information, mentioning Sera as you do so. Tylious' eyes go back to normal as he reads the notes.
"You two entered Death'kul!? Are you insane!? Myself and one other
are the only two suitable to enter there! There are things, and people, inside
that place that you do not want to know about! But yes, I shall help you
invade Death'kul, I was going to on my own mission as it is, hell, who
do you think opened the place?"
Tylious stands up and walks to the door, he stops.
"I go not to help you <name>, I go for my own purposes, I care not for 
your Lordscythe business, I simply seek to free a friend, someone
who knows the reaper as well as I do."
==Objectives==
*Meet Tylious at Death'kul
*Defeat the Reaper Avatar
==Progression==
Tylious looks at you, Sera standing next to him. 
"I still can't believe you two idiots went in there, that place is not
fit for the likes of you! You know not who and what await you in there.
Not even I do, and I know the owner well. Now then <name>, I did say
I know who awaits within, and I doubt he will make things easy
for us, keep your guard up."
The gates open up, revealing a large cloaked figure, a mask with a wicked grin covering his face. It speaks.
"You fools! My master will allow no intruders! No distractions, I shall
stop you now, allowing him to continue in peace!"
Tylious grabs his axe.
"I WON'T LET YOU HURT HIM YOU SONS OF BITCHES!
IF YOU LAY ANOTHER FINGER ON MY BROTHER I WILL
PERSONALLY GORE OUT YOUR
INSIDES AS YOU WATCH ON IN AGONY!"
Tylious charges in as the great being raises it's scythe.
==Completion==
Tylious stands over the great beings corpse, hacking away at it's limbs. Sera walks over to you, a note in her hand.
"I'll deal with Tylious <name>, he is not well. You however, you
should go and gather your allies. We now have a clear
path into Death'kul. Well, you do, I won't be joining, I shall
tend to Tylious, but that is all, this is not my fight.
Let me know what you find of the Lordscythes in there <name>, I'm
sure it will all be of great importance."
