The Foglios have created a Twitter account for Othar Tryggvassen, Gentleman Adventurer. Othar’s Twitter describes Othar’s adventures from his perspective. There is also an archive of the first part of Othar's Twitter posts on the Girl Genius web site and a File:Twitario-Othar.pdf.
At the beginning, the content was sillier and more far-fetched than the main story (Agatha's), and related little to those storylines. It has taken a more tragic and dramatic turn after Othar's Parisian adventures, and has started to provide more connections to some of the developed plots elsewhere.
In one interview Phil Foglio was asked the question of the Twitter's canonicity directly, to which he answered decisively, "Sure. Why not?". Regardless of how it fits within the overall story, it does provide useful information on Othar’s character and personality.
current events of Agatha Heterodyne's story. There is a specific reference to the events in Sturmhalten, Castle Heterodyne being restored and also a passing mention to Othar's retirement (it has been suggested this is Othar's personal term for when he decided to stay on the island with Oslaka).

Adventure the Fourth 
Othar abandons the island (there's slaver wasps. The Autonomous Library, safely underground, cannot tell him much, so he builds an and leaves. As with Paris, all Europa he can observe is devastated. He find deserted crystalline in the wild, larger the further east he travels. Finally, in the ghost town of Heidelberg, he finds another — news from around Europa, and even as far away as Omsk.), and returns to the French mainland, but finds Paris has been by
After being disturbed by the Wulfenbach-Heterodyne alliance news and the sweep of Europa (but Gilgamesh), Othar heads off for the rumored secret city of the Geisterdamen, where he finds a glowing hole, poison dust, and an old "friend" of ours, Tarvek Sturmvoraus. He displays the function of a sort of time machine, and asks for Othar's help. Othar objects on scientific grounds, but after a long pause, we see Tarvek and Othar's consciousness has indeed been cast back in time!by the death of
Adventure the Fifth 
Othar Grantz and dragged before the Baron in the Great Hospital, bringing him into (evidently) the era and timeline that the main comic has been following. The narrative follows him as far as the point where he is with his sister Sanaa; his worrying about her safety sends him into a of how he got banished from his childhood fishing village thanks to his rather too successful resurrection of his recently-deceased uncle. Or actually aunt, it turns out.to find himself back in the/his past, in his young body and in a populated Europe.

Adventure the Sixth
There follows a three year gap resulting from Othar's recording device deleting all his messages for that period. Othar is now in "the southern wastelands", where he falls into a in the town of Sbonkj involving waffles and monster-ranching. The ultimate pettiness of the whole affair sours him on further adventuring and he he's going settle down somewhere and live more quietly, with just a little Spark-killing on the side. He assumes a false identity and arrives in the city of East Walachia, whereupon his account falls silent. Has Othar Tryggvassen, Gentleman Adventurer truly retired?..
Adventure the Seventh
Not quite yet! After a second multiyear hiatus, Othar Corbettite Vault, but the announcement of the creation of a certain new electro-magnetic game prompts him to escape. Determining that he is in some altered timeline, he sets out to (re)unite with Oslaka, which leads him to the locked-down Paris under the rule of Collette Voltaire. He attempts to sneak into the city, and is promptly caught. Dragged before Collette, he convinces her to let him search the city's underbelly, accompanied by a minder in the form of Collette's fairly useless half-brother Claude. They do indeed find a Geister.. but she is not Oslaka, and she is ill and malnourished to the point of delirium. Othar uses Claude to lay a false trail and escapes the city with the Geister in tow. He gets them on board a Corbettite train heading out of town. The train-monks get the Geister patched up, and we learn that she's Eotain, half of the duo who previously kept bumping into Agatha. She claims to be done following the Other's orders, and agrees to tag along with Othar as his "sister" as he investigates nefarious events in Holfung-Borzoi. Judging by the storylines of Twitter and comic will soon converge. Whether the comic will subsume the twitter afterwards or they'll continue alongside is anyone's guess.. He's been contained in a
