At the cove entrance, the already quiet engine on the outboard motor becomes completely silent at some manipulation by the assistant coxswain. [
Private to Goliat: Oddly enough, the very center of the nexus is the cave. In fact, you can be certain the waterfall isn't technological in nature once you reach the cove. Incidentally, this expands the utility of the invisibility superior spell to a point that we can ignore the numbers. You're character is strong enough to grab the zodiac and lift it, then cast the spell so that it covers everyone. The spell does indicate "anything he is wearing or carrying". Besides, the twenty PPE that the spell costs is exactly the amount of free PPE available each melee round.]
Goliat has no trouble cloaking the zodiac with invisibility, and his spell further muffles the already reduced sound of the boat. The waterfall even seems to flow
around the boat rather than splashing on it. Inside the cave is just as it was described by the original infiltration. There are four men, apparently security guards, stationed in the lounge. Two of them occasionally walk the perimeter of the area, together.

2. Being at/on a ley line or a half mile from a nexus point increases the range, duration, and damage of magic spells, wards and circles by 50%. The mage can also draw 10 P.P.E. points from the ambient energy radiating from the ley line and nexus once per melee round (15 seconds). Furthermore, the character's own P.P.E. recovers at the increased rate of 10 P.P.E. per half hour/30 minutes, without meditation!
3. Being at a ley line nexus point or with in 200 feet (61 m) of a nexus point doubles the normal range, duration, and damage of magic incantations, wards and circles. The mage also enjoys a bonus of +2 to save vs magic and Horror Factor, plus his personal spell, ward or circle strength is also increased by +1. The mage can draw an additional 20 P.P.E. points once per melee round. Plus his own P.P.E. recovers at the incredible rate of 20 points per half hour!!
In reference to psionics:
Heroes Unlimited Revised Second Edition page 297:
Range and duration are increased by 50% when near a ley line (within two miles/3.2 km) and doubled when within one mile (1 .6 km) of a nexus point.
Damage from psionic energy attacks such as psi-sword, pyrokinesis, electrokinesis, and telekinesis is doubled when within a mile (1 .6 km) of a ley line nexus point (there's no additional damage from being directly on a ley line or nexus).
The waterfall IS the center of the nexus. The entire island is within one mile of the nexus point; the entire complex is within one half mile of the nexus point.
