Lich was getting tired of waiting. It was the fourth day since he arrived, and the city was still closed.
The day before, a homeless merchant (carrying goods from Ethiopia to Congo through RPA, never staying in a single place for longer than necessary) that Windhoek was in the middle of a revolution and not some protests, as the lords claimed.
The slaves were unsatisfied with their status in the city (it being one of a slave), and started killing everyone who forced them to work. Lich also heard that the city was closed off because the ruling class wanted to win a war of attrition. The battles were heated, but most experienced people knew who will win.
The wild animals, who will enter the city after it inevitably falls.

Lich still had to enter, since there were many things he needed to get in it, like human flesh.
He waited for a wall to fall or the doors to open, but to no avail. More effort would (sadly) be required.
His 3 options would be:
1. Destroying the steel gates.
Impossible. Lich had no explosives.
2. Climbing the wall.
Possible as long as his pick can make a small hole in the walls, but there would be no easy way out.
3. Making a hole in the thick concrete wall.
Risky. He did not know if they were stable enough to not bury him alive.
The choice was obvious, if not nonexistent, the only problem being Lich's lack of ropes. He would have to climb without climbing aid, and falling would most probably be fatal.
But Lich was the king! Nothing could kill him!
With that mindset, he took out his pick, and used it for its intended purpose. The weapon hit the wall, and made a small hole in the place of the impact.
Now, Lich would be able to get in.
