quest help

[gobbles]

Hi, I have some questions about quests that i need to complete and for the life of me i can't find where i'm supposed to go now.

First one is feeding Egnum. I have picked up all of the evilns but i forgot where to find Egnum??

Second question is i don't know where to go to find Ultrax to find the sapphire egg?

Lastly, where is Mehgard so i can talk to the engineer about getting the key?

I just found this forum today and i've been reading so much. You all are so smart with such intersting strategies.

Thanks for any help!
