My 2 Newb Questions

1. I noticed in the vanquish section of guild wiki it says:

From Mouth of Torment (8; requires Nightfall): areas in the Crystal Desert, via Crystal Overlook and crossing into the Arid Sea.

which implies you can cross over from nightfall into Prophecies. It says you can do this through crystal overlook. I've vanquished the whole crystal overlook (and all of NF), and I'm staring at a map of Crystal Overlook now. Where is this connection?

2. Worst of all, so this one comes with a story. I played PvP for the first time this weekend (cause of alliance battles bonus) and quickly hit my faction cap. My team was winning and I only had a few seconds. I wanted to get z-keys and I saw Tolkano had this nice button:

Buy a Zaishen Key with Tournament Reward Points

and then I saw:

Buy Tournament Tokens

so reading too fast (and not noticing his last button) I figured I'd buy all the tokens so I could spend them on z-keys. Once my team split up I realized my error. So my question is: Are these tokens worth anything at all to a PvE player? Can they be traded for gold to anyone?

A map won't help you find this. What you're looking for is a forgotten (one of the serpent dudes) standing near a portal. That is the link.

See here to find out what the tokens are for: http://guildwars.wikia.com/wiki/Tournament_Tokens

So yes, for someone with no interest in serious PvP they're useless. I highly doubt you'd be able to sell them either because anyone who intends to enter the tournaments would be able to earn them themselves.

The link between the Crystal Overlook in NF and the Arid Sea in Prophecies:

Sorry mate, that does indeed suck for you. Next time make sure you get the zkeys from tolkano, not the tourny tokens.
