GH's npc locations

since sigils are extremely hard to get nowadays, unless you can farm lots of ecto in no time (which i cant), i'd like to ask about a few GH's where the normal npc's stand, not the GvG ones... just the merch and such

- druid's isle
- warrior's isle
- hunter's isle

i want to know where the npc's are in these GH's

lets hope anet will make it worth a few z coins, so i can buy it normally
for now i'd like to know where the npc's stand in case they make it a normal price

in case: priest of balthazar and weaponsmith are not needed, as i wont get em anyway, lol

I thought that at warrior's isle the merchant was standing upway the stairs at the far corner to the west of the map. The xunlai chest is in friont of where you spawn, also the skill trader is nearby. However, the rune trader is standing way to far , next to the gate or so. Idk about the other 2 guild halls Ive never been in a guild with them.

It is possible to get one of the Guild related NPCs - I forget which one - to give you a tour of the various GHs before 'buying' one. I believe you need to be a Guild Leader to do this, so you may need to use a sigil to form a Guild first, but you can do this before choosing the GH.

Edit - it's the Canthan Ambassador himself.

The NPS are relatively close to where The Guild Lord is to purchase every thing.

Problem is,if I remember right, the tour only shows empty halls, not with full services.
