House Palantus - Massilia
"Everyone in the party", until others show up at the Palantus townhouse, is Haakon, and Lady Daphne Palantus.
Belenus had been with the group all the way down the river, but had been quiet.
He is one of those supposed to take over the management of House Palantus.
But of course from his very brief introduction, Lady Daphne has no way to know that. Usually, when someone asks immediately for a temple, without any of the chit-chat prior, it means they are in very big trouble.
"Of course there are temples," Lady Daphne Palantus says. "Up there on Temple Ridge. You probably want to steer clear of the Pandemonicum".
She points straight west, and says that from the Palantus townhouse, you can get to the arched entrance of the Temple Gardens at the end of the street in only a few minutes, depending on walking speed.
See the map thread, MASSILIA MAP and Guide item 67 on the Map. You are in the Old Town, just to the east!
Note, it is late in the afternoon, and will soon be early evening.
