We are to investigate the drow general's claims of an army preparing to storm the city, which will require a trip to Thunderspire. Despite its distance we are assured swift travel to Thunderspire, the city council informing us that 'you may use our portal to transport you directly to Thunderspire.'
That's all well and good, but 'how do we get back?' Walking would be quite a chore.
'We have considered that as well—you can use these scrolls of recall we have crafted for just this purpose.'
'Ooh, scrolls of recall', says Krafft, quite enamoured with the idea of magical travel, 'how do these work?' he asks, unfurling one.
'They are spells already cast on to parchment, you merely need to complete the spell by reading the scroll.' As the elder finishes his words, the image of Krafft shimmers magnificently before immediately jumping ten feet to his left, closer to the centre of the hall. The scroll that was in his hand now crumbled to dust.
'That's brilliant! Do they both do that?'
