Perhaps I should have clarified that since this is a free board, I do wish to repair this without buying anything extra, as I might as well just buy another card. I got to work before, so I do not believe the thickness of the bodge wire is much of an issue. It's just gotten slightly disconnected at the end.
I have a soldering iron, a wide range of magnification tools, and I could probably scrape some stuff off, but my area is largely legacy computing at the moment. I do not have the skill, nor the resources to make a professional grade repair. I am more looking for a poor man's suggestion.
All the suggestions are great, but the best suggestion in the world isn't that great for me if I can't use it.
The ink DOES have a higher resistance than regular copper, which could be a problem, A larger problem may even be application as it's a ballpoint pen, and the ink dries upon contact with the air immediately.
I can mask off some parts of the board if needed (not with any Kapton cape, I do not have any), but there is a reason why I do not think I can make solder repair, at least with my bulky iron and no flux (outside of the rosin core). I would most likely end up cooking the board to the point of absolutely no repair. I also do not have any spare board with a break like that, and I am not entirely sure I can break a board in such a manner (or if I would want to, as my supply of junk boards is not immense).
I have fiddled with the bodge wire a bit and I have gotten it to make contact again, but it's a very loose fix. I am up for suggestions, but if it remains as such I might just end up using it in this state.
