I need to get Verona Map
 

I have scoured all available islands and have all the maps accept Verona, Montero and Tekron. I need the Verona map scroll first so I can navigate and visit that island to complete available quests. Where is the map for Verona?

Unless your game has a new unreported bug, you must have missed them. Maps are distributed as follows:

Debir: Scarlet Wind, Bolo
Scarlet Wind: Bolo, Rusty Anchor, Verona (70% probability)
Bolo: Rusty Anchor, Verona
Rusty Anchor: Verona, Dersu, Tekron (50%)
Verona: Dersu, Umkas, Elon, Tekron (50%)
Montero: Montero, Tekron, Umkas, Shatterra (50%)
Dersu: Verona, Uzala
Tekron: Dersu, Umkas, Sheterra
Umkas: Dersu, Uzala, Nameless island, Reha
Uzala: Elon, Nameless island, Reha
Elona: Sheterra, Nameless island, Reha
Nameless: Sheterra
Reha and Sheterra spawn no maps.
