After the Heroes entered one of the most complex barriers that Daneel had ever seen, he couldn't see what was happening inside anymore, but from the way the Head had a smile on his face after he became visible a few seconds later, Daneel could tell that everything had gone well.
He had been hoping that he could catch a glimpse of the fight as everything so far had had the intention of causing awe in the spectators, but it was clear that the Head had made the decision that that might be too much of a risk. If something untoward happened inside and if it was viewed by those watching, it might cause the opposite effect instead, and that would be disastrous, just like it had almost been the case during the Legacy Battle of the Fortress of Unyielding Might.
Hehe, didn't I say I would pump out a couple today? At least 5 chappies coming your way. 2 now, and 3 a bit later.
