This accomplishes several things:
1. Harmony with HttT plot point with Relgorn.
2. A free Ulrek in S19 allows another recall, helping with a stronger I-M.
3. Slightly strengthens him in S18, to deal with I-M now having a side.
4. Dialog in S19 helps characterization of Delfador.
Add character macro for Iliah-Malal.
Make Iliah-Malal an Ancient Lich.
Add Iliah-Malal 'heal when killed' motif from S19.
Improve dialog to better convey reason for running away.
Make portal guardian stronger.
Make Iliah-Malal's castle area look like the one in S11, except ruined.
So they are both elven castles. Slight map tweaks in the area as well.
Use human castles for portal guard so closing portal effects look more natural.
Previously it was going from dwarven castle to ruined human castle.
Give player control of the ghosts and ghouls as they are found.
Update dialog to match ghosts and ghouls joining Delfador.
Enable gold carryover so player doesn't pointlessly wait till last turn.
Lower turn limit, as board is easier with additional units on player side.
Set start gold to 0, so final carryover is lower. With gold and turn limit
changes, it lessens amount in next scenario, but 300 is still achievable,
which is plenty.
Add cave wall to map around tomb. Otherwise a ghost going through the
secret passage causes an akward triggering of the village warning dialog.
Also makes it harder to get to the staff without using the secret passage.
Add dialog and fixe objectives to ensure that player will hear about
the magical artifact (staff) instead of relying on finding a specifc ghost
in a village. This prevents situations where the player can reach the
signpost without having heard of the staff.
It looks like this was done in the days when [move_unit_fake] was the
only option, and thus needed to keep the unit in a certain spot for the
animation to work right. With [move_unit], it is no longer needed.
If Ur-Thorodor moves off of keep and Delfador is next to him, scenario
doesn't end, which looks odd. So prevent Ur-Thorodor from moving.
Make end scene look better by moving Delfador to the keep for meditating.
