Undying Devotion | Requisition of Mage Portal

Good Day,
This will be my second session and we will be taking on 1 of 2 postings:

Undying Devotion

Hey, this is the porter from before. Ok I REALLY need help, I think what started as rats may be connected to something bigger. Not willing to say here, in danger. If you're a real adventurer, please come down by the docks during high tide and ask for 'Mr. Vellorn'.

Requisition of Mage Portal

Good Day Dear Adventurers,

The Mage Guild requests quality Adventurers to reclaim a portal that is rightfully ours! We aren't sure whether this problem is magical or adversarial, but no one has returned through this portal after having been active for the past 2 weeks. The region in question is a magical diamond cavern found beneath an extensive network of ancient catacombs. (All diamonds found within belongs to the Mages Guild and any attempt to collect without approval (goes into long legal jargon))
