No Soul for killing the Kings?

I finally (with help from a beastly lethal character named Euphorius who allowed me to summon them) defeated the Four Kings last night.

My problem is that as I read the Wiki here, it said that from the Four Kings I would receive the Bequeathed Lord Soul?  I apparently need it to kindle the Lordvessel (along with three other Boss Souls), but the Kings didn't drop it. When I checked here on the Wiki, the Soul is listed as a link to the Boss Souls page, but it's not even listed on there.

Did it get taken out?

I haven't been to Anor Londo yet, could the fact that I haven't visited it yet be the culprit?

I was confused about this so I thought I'd drop a line here to see what you guys know about it.

Thank you for your time.

Which is marked by the "Key" icon in my item menu, right?

Ok, cool.  I didn't know that.  Thank you very much. I was honestly afraid that I screwed my game by going out of order.  lol

There is no specific order. You can kill four kings before getting Lord Vessel. You just return once you get the vessel to unlock the remaining areas where the other lord souls are.

Ok, I see now.  Thank you both very much!
