I had to look into this, because I love me some good mystery. I found that Innkeeper's Daughter WowHead page but couldn't find the word 'Gaskeldo' anywhere. I opened the Page Source and did a Ctrl + F to figure out what would cause this page to show up on google search result and found the name coming up in a comment: "Yes. Stay very clear of gnome warlocks. -Gaskeldo, a gnome warlock". I can't seem to find that comment anywhere other than the Source Code, not sure what that's all about.
My guess would be that this one's just a coincidence, perhaps a randomly generated name. Still make for a cute, even if unintentional, message though ^^
