The Quest From The Trainer

There was no way that players could summon each other; the average NPC didn't have this ability either.

Could it possibly be Remulos?

He was the most likely to summon him, or perhaps it was the Elder of the Blood Fang Worgen. After the curse was lifted, his strength grew and he was no longer to be underestimated.

Lu Li wasn't left confused for too long; the changed environment put him on guard.

He knew that the few NPCs who could have possibly summoned him had no bad intentions.

But...

Lu Li didn't even hesitate to dive forward, regardless of what was ahead of him. The piercing feeling of danger told him that if he didn't move, he would surely die.

His reactions surprised his ambusher, even though that was his intention. If the ambusher wanted to kill him, he would have made his move in silence. After all, this was an expert Thief who had assassinated King Llane.
