The following points are connected by Hortha Vines:
- Firebase November (Firebase Zulu) - The Marooned Shores (Cascade Archipelago)
- The Chanting Islands (Cascade Archipelago) - Path of Tears (The Chantry)
- Path of Rage (The Chantry) - Path of Madness (The Storm Palace)
The Firebase Zulu intra-Shard portals drop you off near the Hortha Vine mouths at The Marooned Shores, the Path of Tears, and the Path of Madness. This makes it easy to get to the "far end" of each zone except The Storm Palace, by going a zone past where you want to be and taking the vine back.
Example: To get to Lt Volkov on Firebase November quickly from General Hammond. Take the ring portal to the Cascades then the Hortha vine back to Firebase November.
