The sketch artist's name was Birger Torvesson, and he was the son of a talented woodworker named Torve Niallesson, a great descendant of Norse-Gaelic bloodlines. Torve's great great grandmother had been a Gaelic Celt descended from Coirpre mac Néill, one of the legendary Kings of Tara which existed in Dalraida since old times. Torve's great great grandfather had been a Swedish Norseman descended from Egil Vendelcrow of the House of Scylfings, which itself had belonged to the House of Ynglings long long ago. Birger Torvesson had followed in his father's footsteps by becoming an artist. Only instead of working with wood, Birger decided to make sketchings instead. He knew all different styles of Celtic knotwork, or Icovellavna and Old Norse sketchwork including the Vendel style, Oseberg style, Broa style, Borre style, Jelling style, Mammen style, Urnes style, and his personal favorite, Ringerike style which he used most often, especially when drawing the flora and fauna he was witnessing on the river banks of Xamoyos.
Birger would make light sketches of the sharp-toothed Xamatohades pliosaur that his team had encountered underwater, along with the small pod of manatee-like Xamatospondylus fish eaters that had surfaced around the convertiboat. He drew the rather large Xamatosuchus crocodilians which were basking on the shore, and the small pterosaurs that were flying around them. He took a few small notes, writing in Old Norse calligraphy while also making sketches of some of the plants and trees near the river bank. Jonah Marksberg was still surveying the area and keeping a watchful eye out for any more predators which might attack, while Svegdir Staghelm focused on piloting their small-sized vessel closer to the inlands. They were heading through Lake Dinesair, straight into the heart of Dracos Valley, but after their close encounter with the long-nosed pliosaur, Svegdir would not dare to lift back the protective bimini-like rooftop on their convertiboat until he was sure they had made it safely to the shore.
"How's our oxygen level?" Svegdir Staghelm asked curiously, seeming remarkably calm for someone who had almost just been eaten. Jonah tapped his finger against the strange barometric apparatus on the center console beside him. This small glass-like vertical narrow tube system measured the atmospheric pressure, temperature, water and oxygen levels inside the convertiboat without using batteries or electricity. It also provided a fairly accurate reading for the atmospheric pressure, sea levels and temperature outside the boat as well, giving the small band of Empyrean Norse explorers a better understanding of the environment around them.
"70%, looking good so far, we've got about another week or two before we start to suffocate in here," Jonah replied, before checking the other readings on the strange apparatus before looking around.
"I'm not seeing any water levels inside the boat. Nothing on the floor either. Our armour is still looking good. I don't see any punctures. Everything looks alright", Jonah informed Svegdir, who was too busy controlling the boat to look behind him.
"That's good. What is our current location?" Svegdir Staghelm asked as he steered the karve closer to land, passing over the center of the lake. Jonah Marksberg would look at the strange Norse barometric apparatus again before looking at the other two karls behind him, who were already pulling out their magnetic water compasses and small wooden sundials. One of them would pull out his portable silver canteen mess-kit and poor a small bit of water into a pot, placing the round 70mm wooden compass into the water while the other karl waited for an indication of where to place the small wooden sundial. Within about thirty seconds, they had their answers from the gnomons on the shadow board.
"We are about seven feet below sea level, heading south-south east. Both gnomons are in alignment, one with the latitude, and the other with the sun. It's about mid-day," Jonah Marksberg commented, nodding to the karls behind him as they put their belongings away. Karvi-1 was coasting smoothly now over Lake Dineasair as the Empyrean Norsemen prepared to reach the shore and step out on to land for the first time in months since they had journied across the stars.
