Glenno, from Ultima VII
The Avatar found him in Ultima VII, at the reception desk at the evening. He was a man of little words, stating the entrance fee would be 300 gold pieces. After accepting the hefty sum, Glenno was more than happy to advertise the house. When he saw Spark, he asked the boy how old he was. After some back and forth, Glenno simply shrugged it off since he was the management, and allowed the boy to enter as well.
Afterwards, Glenno gladly gave to the Avatar, now a paying customer, information about all the various things inside the House of Baths, and offered wine and ale for further relaxation.
