Strange new demons have begun to appear in Sanctuary, and a mysterious woman who has tracked you down seems to need your help.
The two of you must venture to a forgotten crypt to investigate what may be the source of the strange demons and you must head there before things are too late.
You will need to make your way to the forgotten crypt and see what is in store, which will include a newfound power as well as another individual who shares the same interest in the demons.
A Deceitful Incursion Quest Walkthrough
As you arrive in Kyovashad, a stranger appears to be waving at you, who is later revealed to be named Sayeena. (Speak with her to continue)
After speaking with Sayeena, you will need to make your way to the forgotten crypt that she has mentioned and this will be a short ride to the east from Kyovashad.
The two of you will eventually reach a small entrance and after speaking to Sayeena, you will be able to go inside of the forgotten crypt. (Ice-Rimed Crypt)
Fight your way through the hoards of strange demons until you reach a knight named Jarius, who will be slaughtering demons in the area.
Speak with Jarius and he will tell you about his crusade (To wipe out all the demons in Sanctuary) and he will invite you to join him.
Head with Jarius into the next area and continue making your way through the Ice-Rimed Crypt as you fight through more of the strange demons.
A Mysterious Demon (Belial) will appear once you reach the end of the Ice-Rimed Crypt and it will attempt to convert you but it fails due to Lilith’s Blood running through your veins.
Instead, it summons the Apparition of Kirma to feed on you and you must slay this beast along with the other demons that spawn with it.
Once you have slain the Apparition of Kirma, Sayeena and you will need to speak with her to complete the quest.
A Deceitful Incursion Rewards
Defeating the Apparition of Kirma will unlock Kirma’s Sparks (Boss Power) and this will be the very first Boss Power that you get in Season 8.
This also unlocks the Boss Powers feature that is available during Season 8: Belial’s Return and there will also be a quick tutorial about it.
Rewards for the quest itself include XP, Gold, and an Herb Cache that you can open to get Bundled Herbs and possibly some equipment early.

Verdict
It appears that the Mysterious Demon turned out to be Belial, the Lord of Lies and it looks like he is behind the demon infestation.
Belias attempted to convert you into one of his own but thanks to Lilith’s Blood, you were unaffected and this can be a huge advantage.
A new journey awaits you now as you have teamed up with Sayeena moments ago and now with a knight named Jarius as well.
