Ah, mate thats just Chromie. Shes not really a gnome. Shes one o’ them Bronze Dragons.
I know one o’ those sorts who takes the form of one of them Sethrak blokes from Zandalar.
If you ever want to head home just do so. Chromie or some other Bronze will send you to the right time as you pass through the portals or cross the oceans. They keep tabs on ye.
