Lolorito was wanting to side with the Garleans and do business with them. He owns the Goldsmith and Weaver guilds, he owns the Brass Blades (think of the Koch bros but by himself and in terms of evil and shadowy-behind the scenes things). He was always going to be a threat to the Sultana and he always wanted more. Niellefresne stole an important dagger from him in 1.0, the Heartstrike dagger. It was a dagger that was said to have the ability to revive the dead or atleast let one commune with them, Niellefresne was stabbed in the back by a STILL unknown assassin before Mumuapo (the 1.0 THM guild leader who was relieved of duty by the Sultana after the Calamity) could return from the guild with certain items for the ritual they were to perform.
Fast forward a bit to 2.0 and Lolorito had gotten rid of most of the whipper snappers from the original 1.0 story (Nielle, Greinfarr, F'lhaminn) and had formed up the Alacran to do more of his shady works. Early in the story line the Alacran had stole the Sultana's crown (funny thing was it was made to be seen as an Ascian plan) and were to exchange it for a powder/item that was said to be the same substance that the Sil'dih had used to start their zombie army (which lore wise the Ul'dahns actually barricaded the Sil'dihns inside their city and the zombies ran amuck).
Teledji Adeledji was absent in 1.0, we never actually met him. The only time we saw him was when Raubhan had his speech and the Syndicate stood behind him, I think he didn't have a mustache at the time.
