You can actually extrapolate a bit from this!

Nine Inch Nails was formed in 1988 and did not have any releases until 1989, making it unlikely that Auntie listened to them before this time. Lara was 21 when she crashed in the Himalayas and got disowned by her family. Since she was born in 1968, this happened in 1989.

After the Cambodia accident, Werner suffered from nasty ligament tears in his knee and had to put adventuring aside for a bit. He retreated to Vienna to attend physiotherapy and focused on his musicology career track. The Iris was locked away in his father's museum, awaiting proper research.

Two years later, at age 18, Lara was sent to a finishing school in Switzerland. As she felt that she had won the Iris fair and square, she decided to "pay a visit" to the museum and took back what was hers. She stowed it away in a safe place before going back to her classes as usual.

Werner was extremely annoyed with this and his father was livid. He tried to persuade Lara to hand the Iris back time and time again, but she merrily refused. This went on for a few years until he learned that her plane had crashed in the Himalayas after a ski trip. Hoping to find her alive and maybe even filling her with gratitude for saving her life, Werner went to Lord Croft to acquire funding for a rescue party. The Crofts were not all too keen on this, however. The only people who wanted to help him find Lara were her punk aunt with the evil corgi and her fiancée the Earl of Farringdon.

Looking around for Belloq content and finding he's just mainly non existing or shipped with Indy and it's pretty disappointing overall.
