"Us fulmars have a saying - taevas on maa tiiva - The Sky is Land to the Wings."Vesipoiss, often referred to simply as Vesi, is a young Northern Fulmar that Jascon and his friends encounter on their way to the Kingdoms of Steel. At first they dismiss him as a stinky seagull, but as he guides the three to Sealand, he reveals that the fulmar race is one of the oldest, with their knowledge rivaling that of owls.
He speaks fluent Kajaka, an ancient fulmar language that predates owl Krakish, and has mastered the acient art of Lustleek, carrying a live flame in one's crop.
Jascon, Edda and Sturla come across Vesipoiss after a day, a night and a morning of continuous flying. Desperate to land, Jascon approaches what he thinks is a seagull. The bird corrects him, telling Jascon that he is in fact a Northern Fulmar, a prehistoric seabird far removed from the seagull. He introduces himself as Vesipoiss - not a conventional name, he says, but more like a pet name given to him by his mother. He's fluent in Kajaka, the language of the fulmars. Sturla hypothesizes that Kajaka is a very old language, perhaps even pre-dating Krakish, and notes its similarity to Kratean.
Vesi, as he likes being called, goes on to mention the ancient art of Lustleek, where fulmars, through much practice and meditation, are able to keep a live flame going within their crop. The oil in the stomachs of fulmars has long been used by the Others in oil lamps, but Vesi explains that fulmars themselves have come to utilize it, making them the only other known birds other than owls to tame fire.
Vesi leads the three owls to Sealand - not exactly an island, but rather a disused ocean military base off the coast of England. There, the owls get their first glance of live Others, or humans, as Vesi calls them. He explains what he knows about humans to the owls, but does not accompany them to the mainland, fearing he might lose his flock.
Upon their return to Ga'hoole, Sturla convinces Vesipoiss and his father to come to the Great Tree and meet his mother, Otulissa, to tell them more about the Kajaka language. They discover that, indeed, it shares a remarkable resemblance to Kratean.
They name the newly discovered Vesimere Bay in his honor.
- Kajaka is, in fact, modern-day Estonian. Kajakas is Estonian for gull.
- Vesipoiss was originally a seagull named Spike.
