My great sense of smell, wasn't actually quite useful, because all the smelling part was done by my sweet Skitty. I wasn't quite sure what this altar would offer me, but having some faith in my luck, my skitty and by NPC [sorry i forgot her name], i entered into the altar, hoping to find the great dragonair.

Suddenly (well, "sudden" may not be the best choice of word after three months), Solana stands - or rather floats - before you in all her glory. She stares at you, as if taking in all that you are, and then glances toward the Pokeballs in your belt. "This is a grass challenge," she murmurs. "Please come back with a grass type in your party."

A strange powder seems to be raining from the sky, and you wonder what it is and where it's coming from before--

You wake up just outside the shrine. Perhaps it would be best to follow Solana's advice and get a grass type.
