Made a thread too, lawl ^^;
So, right now we have
Malzahar + Kog'Maw leading
Pantheon, Karthus, Cardmaster and Nasus chasing them
Ezreal, Mordekaiser and Janna fooling around?
Tryndamere and Gragas somewhere there too
Ryze and Veigar following the main group
Cho'Gath preparing the ritual in Icathia
Katarina coming after him
who else? We need to sort of tidy up the action, otherwise we get a lot of 2-3 person situations which are completely unrelated to the "main course".
I'd also ask everyone to actively think of a reason to be in the Shurima Desert, going towards Icathia (like Pantheon or Karthus have), and not just going by the "oh look I was casually passing near a lost city nobody could find for ages and decided to have a picnic". Let's keep it neat and interesting, gentlemen.
Also, two personal observations of mine. I'd like to underline the "no puppeteering" rule, i.e. no controlling the actions of the other characters. Also, no metagaming. Your character is NOT you, so he does not share the player's knowledge. Keep that in mind, please.
EDIT - We should all meet up in a chatroom. I propose http://www.roarchat.net/
