Mordremoth.... Wiki *Spoiler in link*
Technically we don’t have any guarantee that there are only the dragons known to the player. Mordremoth hadn’t woken up yet before this patch and wasn’t even known to most of the characters beyond potentially the Inquest based on the CoE. For why Mordremoth, maybe there is a deeper connection to the Sylvari we don’t know yet and Scarlet was able to be corrupted when she left the protection of the pale tree. As for the wiki I’d assume that’s all player edited but don’t quote me on it.
Since it seems that we sre going down the earthy route of Tree god dragon of doom and shrooms and Sylvari’s, i hope A-net go more into the second Sylvari race that was shown in the Sylvari PS about Malyck and a second grove with its own mother tree.
There is actually nothing at all that suggests that all Dragons were awake before LS Season 1.
I would say it was quite the opposite.
We knew that there were (at least) 6 dragons, but we only ever heard and/or saw effects (as far as we know) of 5 of them.
