where is he?

В океане Процея, странствующий торговец, останавливается у островов: Номакс, логово Кракена, остров гоблинов, курорт Гравис, остров Избранных.

If you don't speak RU, here, this is the route you can follow when searching for this ship: Hypnos's Eyes, Gravis, Goblin Island, Eternity Isle and Sublime Isle.

I found it at Hyonos's eyes 4 secs before it disappeared lol

There are 2 more islands that it can spawn at including the 4 listed previously. Full list:
Sublime Island
Eternity Isle
Niheltalop's Thoughts
Goblin Island
Gravis
Hypnos's Eyes

It spawns at the start hour and stays 30 minutes. The easiest way to find it is to swap channels near the 6 islands listed above. You can also sail half way between Goblin Island and Niheltalop's Thoughts to check two islands at once. You can also park characters at each island and swap characters to save time.

Erscheint auf einen von 6 Inseln, immer um 5 nach und ist ca. um halb weg.
Z.B: 11:05 bis 11:30
Handelsschiffe verkaufen nicht immer das gleiche and der gleichen Insel.
1. Insel der Erhabenheit
2. Insel der Ewigkeit
3. Niheltalops Gedanken
4. Goblininsel
5. Gravis
6. Hypnos’ Augen
