The "Traveler's Gate" allowed Dr. Schneider to briefly appear at Midshire Fort, but as any items with supernatural power couldn't pass through the gate, aside from the key to the door, the doctor also handed Shard a suitcase containing spellcasting materials and ritual materials, asking Shard to help bring them to Midshire Fort and to set up the peripheral rituals in advance, to assist in weakening the power of that demon.
"Would the locals of Zaras be willing to trade for this gate?"
Shard asked, holding the key. The doctor nodded his head and patted his own chest:
"Don't worry, I'm quite popular with the locals. They do have their eyes on your mirror; it's quite a clever prop for when one is being chased or needs to eavesdrop. However, they are not willing to compensate you with more than 50 gold pounds, so come back again tomorrow night to talk."
"Hmm?"
