yeah, there're others commanders and we're the "first commander of the pact". https://wiki.guildwars2.com/wiki/Pact(check references section) Actually it's The Commander and A Commander. There are Multiple Pact Commanders, and in the case of assault on Mordremoth I recall it being clearly stated that "other commanders" are leading the assault on the head "up above". I am not quite sure on the timing of that one, the assault on the main gate takes a fair bit more time, especially with claw fight involved, than entirety of the story instance combined, and both are supposed to start at the roughtly same time, (we give signal to start the assault as we enter the doors). And after destroying conversion chamber, the frost citadel is supposed to crumble, all together, while apparently the side we are at doesn't? Not to mention that in case of frozen doors, in the instance efram, needs to be instructed how to deal with them but in the meta his like "step aside I've got it". Don't get me wrong, I don't deny they are supposed to somehow happen in the paralel, it's just that the way both were written, and supposed to intertwine, it's kind of messy how exactly they intertwine in there. I personally just call the other character we represent the Adventurer to separate them for less confusion on their roles in the game due to their stories happening at the sametime but the game does not clarify which role we are in unless more directly mention in the Main Storyline for time placement. After all there is only one "Commander" the Main characters are with and known for each main storyline events since GW2 story began but there are many other commanders the Main characters do not know about or only seen passing by with the Adventurer being among them.
