Lisandro needs a way into the convention. It’s starting up in a few days and he doesn’t want to get left out. There’s a tavern that gives discounts to delegates; he visits and offers to pay someone to bring him in as an ‘assistant’. The exact same amount as the stipend, since the archmages decided thats how much a delegate costs. 

It’s not hard finding sortitions willing to take him up on the offer. The hard part is finding one who has the right attitude about it.
